Yes batter been changed twice Incase was duff battery
Had another fob and no that doesn’t work either though I didn’t expect it to as was from another car
As said the indicators no longer flash at all even when locking manually and I can’t recall if did before the remote ceased working

Yes I changed battery twice Incase replacement was due
I have another fob from another vehicle which didn’t work which I was not surprised at since it was not from my vehicle
I tried all the re syncing procedures for that key but didn’t work
